Hello,
I'm trying to understand how longhorn recurring backups works. I am running into an issue where longhorn tries to take backup of a bigger PVC (around 120GB).
The problem is that it the backup job will store the pvc blocks in the containerd overlays FS images on the host disk, which in turn fails due to missing storage in /var/lib/rancher/rke2/agent/containerd/io.containerd.snapshotter.v1.overlayfs
It this really how longhorn backups work? It would then require that I increase my OS disk by 500+ GB to fix it... or is it an error?
I am running Longhorn v1.8.0 with RHEL 9.5
